UNITED STATES PATENT OFFICE.

MICHAEL TELECHEFF, OF ST. PETERSBURG, RUSSIA;

GUN.

To all whom it may concern:

Be it known that I, MICHAEL TnLEoHErr, general-major, subject of the Emperor of Russia, residing at St. Petersburg, Russia, Mitninskaj a Quay No. 7 ,have invented new and useful Improvements in Guns, of which the following is a specification.

This invention relates to firearms having a plurality of barrels located one above the other and the object is more particularly to.

provide a novel form of gun-lock, which is constructed or formed according to the number of barrels in the firearm, said lock being rotatably pivoted on a vertical axis, placed laterally of the axis of the bore of said barrels. The said lock is held in locked position by means of abolt having one or more recesses corresponding to other recesses in the lock, in order to permit the opening of the latter before the bolt is entirely withdrawn.

Embodiments of the invention are shown in the annexed drawing in which- Figure 1 is a side elevation partly in sec-' tion of a firearm with two barrels seen from the left showing a closed and bolted lock with the hammers mounted in the movable lock. Fig. 2 is a plan view of Fig. 1. Fig. Fig. 4c shows a side elevation of the lock bolt. Fig. 4 is a rear elevation thereof. Fig. 5 is a partial longitudinal section of the firearm showing the lock closed-and bolted. Fig. 6 is a section on the line 66 of Fig. 5. Fig. 7 is a cross-section on the line 77 of Fig. 5. Fig. 8 is a side elevation of the closing lever. Fig. 8 is a plan View thereof. Fig. 9 is a partial sectional side elevation from the left hand side showing the lock released. Fig. 10 is a partial sectional side elevation from the right hand side showing the lock and bolting parts in the same position as shown in Fig. 9. Fig. 11 is a similar View to Fig. 9, showing the lock open. Fig. 12 is a section on the line'1212 of Fig. 11. Fig. 13 is a partial longitudinal section of a modification of the invention, the lock being shown in closed position. Fig.14 is a detail elevation showing the lock and bolting parts ofthe construction of Fig. 13 from the right hand side of said figure. Fig. 15 is a sectional detail view of the hammer shown in Fig. 13. Fig. 15 is a section on the line 15*-15 ofFig. 15. Fig. 16 is a plan View of the closing lever shown in Fig. 13.

or more barrels located one above the other, the casing .g, the breech block 70, the bolt 7, the closing lever g and the triggers a. The casing g is connected in any suitable manner to the barrels, and the upper barrel Z carries the sight bar a which is provided with a groove in which a projection g of the casing 9 engages while a plate p bears against the rear surface of said projection g and is fixed to the bar o by means of screws 39. The lower barrel Z with its extensions a and a is secured to the casing by means of a screw 6 and a bolt 6 The lock bolt 1" is displaceably located in a vertical recess g in the interior of the casing 9 while a second vertical recess g receives the pivot k of the laterally oscillating lock is. The rotary axle k of the said lock is bears between the pivot 70 and the pivot 11 carried by one of the projections c of the bar '0. The wall of the easing opposite the axle 70 is slightly curved and provided with an inclined extension 9". The closing lever Q, the triggers 2' and the safety device hereinafter described are located in the lower part of the casing. The lock 70 is provided at one side with cavities 70 correspondingin number to that of the barrels and which serve to facilitate the introduction of the cartridges. The other side of the lock is provided with a straight or smooth surface is at the front part of which is located the enlargement m. A recess 70 is provided at-the rear of the surface 76* into which the extension 9 of the casing g enters when the lock is rotated or opened. Curved projections k are provided at the rear of the lock, the center curve of which is the axle k of the lock is. A recess 70 corresponding to the recess 1" in the bolt 1" lies between said projections. In the lock itself are housed the hammers s and their springs f to which the bar 8 serves as an abutment. The trigger. lever t and spring 2? acting thereon are located in the lower part of the look, while projections 10 are provided at its rear part between which the cooking levers It, engaging slots 8 in the bolts, are located. The bolt 1*, whlch secures the lock during firing, has in cross-sectlon the shape of a prism or a frustum of a pyramid and is provided with the recess 1' which as prethe recess 1* as Well as the projections 72 and the recess 70 of the lock 71 are given such dimensions that the projections can enter the corresponding recesses each time the lock is opened. It now the bolt 1" is placed in such a position that the lower projection is of the lock enters the recess 7" in the bolt, then the lock is released and can be rotated into the open position shown in Fig. 12. If the bolt, however, is raised, the projections on both parts bear against each other and thus prevent rotation of the lock. The bolt 9* will thus receive the recoil of the lock 7: during firing and transmit same to the casing 9.

The cocking levers 7L disposed between the extensions 70 at the rear part of the lock are each provided with an extension or nose n which bears upon the levers t in a tensioned position. A closing lever g pivoted at g in the lower wall of the casing g is connected to the bolt 1 by means of a link u. The said closing lever g has two noses 9 g at its right hand side which produce the opening and closing of the lock is by either the nose 9 or Q2 respectively acting against a projection 70 provided on the right hand attachment 70 of the lock. The closing lever g is also provided with an extension 9 which when the lock is opened bears against the extensions n of the cocking levers and locks the latter. When the lock is closed, the said extension 9 prevents premature release of the cooking levers.

The operation of the firearm thus far described is as follows: When after firing, the breech is to be opened, the lever g is moved downward about its pivot 9 and upon this movement the extension 9 commences to cook the cooking levers 72 by acting upon the extensions 92 thereof. The bolt 1" which as aforesaid is connected to the lever g by the link u will be simultaneously moved downward in the recess 9 and as soon as the upper projection r of said bolt arrives opposite the recess 70 in the lock is (Fig. 9), the projection g on the lever g has moved into contact with the projection 70 of the extension 71 provided at the right side of the lock (Fig. 10) and when the lever g is moved farther bears against the front surface of said extension, thus producing the rotation of the lock 70 about its axle 70 and unchecked by the projection r of the further downwardly sliding bolt 7", the lock moves to its completely open position shown in Fig. 12 which it assumes as soon as the interior 7 wall of the recess 70 bears against the inclined extension 9 of the casing wall. At this moment the bolt 1' has also reached the end of its movement (Fig. 11). When the lock is to be closed, the lever g is returned to its original position whereupon the projection or nose 9 which during the open position of the lock bears against the projection 70 of the attachment 70 (Fig. 12) now abuts against the projection k which causes the lock to be rotated back into its closed position. Simultaneously with the rotation of the lock the bolt 1" is moved upward without afiecting the movement of the lock. hen the latter has reached its closed position (F igs. 6 and 9), the projection 70 is out of the path of the nose 9 on the closing lever 9 (Fig. 6). By further moving said lever g, the extensions 12 of the cocking levers engage the levers t and the bolt 1' slides into locking position, that is to say, its projections r engage the projections is of the lock 7c. Release of the cooking levers h is consequently impossible until the lock is has reached its closed position.

A modification of a firearm with two barrels is shown in Figs. 13 to 16 according to which the laterally oscillating lock 70' is located in the casing g and is locked by a bolt 1". This form differs from that one shown in Figs. 1 to 12 by the fact that the springs 7& of the hammers h are secured at the rear wall of the casing 9, said hammers being pivoted on the pin 9 of the closing lever g. The triggers a are also formed in one piece with the levers t and the bolt 1" as well as the lock have several co-acting projections and recesses. The bolt 1' has also a nose T which engages a hook g of the closing lever 51.

lVhen releasing the lock the bolt '7' moves under the influence of the hook of the lever 9 so far downward, that its projections r are opposite the recesses 70 in the lock. At the same time the hammers h are tensioned by the extensions q of lever q acting against the abutments 7L on the hammers. By further turning the closing lever 9 about the pivot g, the nose r and the hook Q5 are disengaged and meanwhile the nose 9 of the lever g has arrived in contact with the projection 70? and opens the look by the pressure exerted upon said projection 70*. When the lever Q is returned to original position, the lock is closed in the same way as already described with reference to Figs. 1 to 12. When the lock has reached its closed position the hammers bear against the extensions t of the triggers 2, that is to say, they are tensioned. Release of the hammers was consequently impossible previous to this position of the parts since the projection g of the lever g prevented engagement with the extensions t of the triggers z. Directly the lock has reached its final closed position, the nose r of the bolt 1- engages again the hook g on the lever g and the bolt can be moved back to its locking position. It is to be remarked that the closing lever Q can also be located in front of the trigger bow if required.

In Fig. 13 8 indicates the firing pins acted on by the hammers h and 8 enlarged slotted ends of said pins traversed by a pin 8 f f designate springs acting on said pins to return them to normal position.

What I claim as my invention and desire to secure by Letters Patent of the United States is 1.
